About this study

This is a phase 1 study evaluating the safety and maximum tolerated dose of Liothyronine (T3) in subjects with multiple sclerosis

Read the detailed description

This is a pilot, phase I, placebo controlled clinical trial of short-term high-dose thyroid hormone to promote remyelination in MS. Permanent clinical disability in MS is likely caused by the neuronal damage and degeneration that follows recurrent demyelination with progressive failure of remyelination. Thyroid hormone (TH) is required for central nervous system (CNS) myelination during development, and CNS remyelination in animal models of MS, a process similar to developmental myelination, has also been found to be promoted by TH. This study will ascertain the safety, tolerability and maximum tolerated dose of TH in people with MS, explore reliability for a potential signal of treatment efficacy and mechanism, and optimize procedures for a full scale clinical trial to evaluate the efficacy of pulsed TH for promotion of remyelination in MS.

The safety and tolerability of this treatment will be assessed using subjects' self-report of symptoms, the validated Hyperthyroid Symptom Scale (HSS), and blood pressure measurements. a

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Liothyronine sodiumDrug

    Also called Cytomel

    Subjects will be divided into 4 groups of progressively escalating doses. Each group will have 6 subjects 4 will receive the active treatment and 2 will receive the placebo. The first group will receive 25 mcg twice daily for one week. The second group will receive 37.5 mcg twice daily for one week. The third group will receive 50 mcg twice daily for one week. The forth group will receive 75 mcg twice daily for one week.

  • PlaceboDrug

    Patient will receive a matching placebo to take twice daily for one week.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Determine the Maximum Tolerated Dose (MTD) of Oral L-T3 in Subjects With MS

    MTD per protocol (dose level one category below dose at which study was stopped due to intolerance or meeting criteria for cessation)

    Measured: 1 week

Secondary outcomes (1)
  1. Reliability of Visual Evoked Potential (VEP) Testing (ICC)

    P100 latency will be compared before and after treatment with L-T3 in subjects receiving the active treatment to assess reliability of the test for future assessment of treatment effect.

    Measured: 1 week

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Liothyronine sodium in people with Multiple Sclerosis, run by Oregon Health and Science University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Nov 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Nov 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Determine the Maximum Tolerated Dose (MTD) of Oral L-T3 in Subjects With MS (time frame: 1 week). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02760056, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Nov 2018.
